Solar Deals Australia: Current Offers on Panels, Batteries and Inverters

Solar Galaxy runs seasonal and government-backed offers on residential and commercial solar systems, battery storage packages and inverter upgrades. Each deal listed below is current as of the date shown. We update this page as new offers launch and remove deals once they expire.

Australian solar deals fall into 4 main categories: manufacturer promotions, installer package discounts, government incentive windows and battery bundle offers. Each type works differently, and they can often be combined for a larger total saving on the same system.

Manufacturer promotions come directly from brands such as Sungrow, Tesla and Fox ESS. These are usually tied to product launches or stock clearances and run for 4 to 8 weeks.

Installer package deals bundle solar panels with inverters or batteries at a reduced combined price. The saving comes from buying power with distributors and the efficiency of a single-visit installation.

Government incentive windows create natural deal timelines. The federal STC rebate under the Small-scale Renewable Energy Scheme decreases each year until 2030 as the deeming period shortens. State programs such as the NSW Peak Demand Reduction Scheme and Victoria Solar Homes Program have fixed funding pools that close once allocated.

Battery bundle offers pair a solar panel system with storage at a price lower than buying each separately. With residential battery prices dropping 18% between 2024 and 2026 according to the Clean Energy Council, bundle pricing is now more accessible for homes across Sydney, Melbourne, Brisbane and Perth.

The best time to buy solar is during Q2 (April to June) and Q4 (October to December) when installer deals, EOFY tax incentives and manufacturer clearances overlap. These two windows consistently produce the lowest effective prices across the Australian market.

April through June is the strongest period. Businesses install before the end of financial year to claim the instant asset write-off or accelerated depreciation. Installers increase capacity and offer deals to fill the schedule.

October through December is the second-best window. Spring brings longer daylight hours, so newly installed systems start generating returns immediately. Distributors often launch end-of-calendar-year promotions.

Two factors make waiting risky. The STC rebate reduces each January as the deeming period shortens, so the same system attracts fewer certificates in 2027 than in 2026. Electricity prices from retailers such as AGL, Origin Energy and EnergyAustralia have risen an average of 8% to 12% per year since 2022 according to the Australian Energy Market Commission.

Combining a Solar Galaxy deal with the federal STC rebate saves most households between $3,500 and $6,000 on a standard 6.6kW to 13kW system. Commercial customers installing 30kW to 100kW systems typically save $8,000 to $25,000 or more when deals align with government incentive windows.

Each deal page lists the specific saving amount. All prices include the STC rebate applied at point of sale, so the deal discount is on top of the government incentive.
